Summary
The gene expression programs need to be precisely regulated and the misregulation of these programs can cause a broad range of human diseases. My research will focus on two protein complexes, which heavily contribute to the regulation of gene expression. My study will open a new path for developing new therapeutic strategies.
The Bacterial Type IX Secretion System In Polymicrobial Dysbiosis And Chronic Inflammation

Summary
Periodontitis (severe gum disease) affects 1 in 3 adults and has been linked with heart attacks, cancer and dementia. I will lead a multidisciplinary team investigating the interaction between disease causing bacteria in the mouth and the immune response which results in destruction of the tooth’s supporting tissues and allows bacteria to enter the blood stream. The expected outcome is the development of a novel therapy which will stop progression of disease associated with these pathogens.
Counteracting Age-associated Neurodegenerative Diseases Using Chaperone-based Amyloid Disaggregases

Summary
In neurodegenerative diseases such as Alzheimer’s disease, proteins form clumps through changes in structure due to mutations or proteotoxic chemical insults. The formation of these toxic clumps causes brain cells to die prematurely triggering symptoms such as dementia. I have identified a molecular machine in human cells that efficiently clears these clumps. We are now developing strategies to activate this machine to repair damaged brain cells to slow/reserve neurodegenerative diseases.

Summary
Cells sense and respond to a variety of stimuli by activating different signaling pathways. The Wnt pathway is important in embryonic development as it controls cell division and specialization. In adults, dysregulation of this pathway can lead to aberrant cell division and cancer. This proposal will use structural biology to look at several steps of this pathway at the molecular level. This will provide answers on how this pathway works and will lead to new ways to target it therapeutically.
Structural Biology And Therapeutic Targeting Of Axon Degeneration

Summary
The molecular mechanisms underlying SARM1 (sterile alpha and TIR 1) function will be investigated, which will allow design of inhibitors of axon degeneration, which can be developed into therapeutic agents for neurodegenerative disease. Outcomes are not only anticipated to support excellence in basic research, but have potential of assisting health sectors and the economy, by reducing the burden of prevalent neurodegenerative diseases such as peripheral neuropathies and traumatic brain injury.
Using Protein Structure And Dynamics To Facilitate Drug Discovery

Funding Amount

Summary
G protein-coupled receptors (GPCRs) are the largest family of membrane proteins in the human genome, and drugs targeting these receptors account for 35% of marketed drugs. This project aims to determine atomic-level structural information of how drugs bind and specifically interact with therapeutically relevant GPCRs. Outcomes of this research will facilitate the design of future development of selective and effective drugs.
